An Integrated Conceptual Expert System for Flood and Water Pollution Management
One particularly practical role for an expert system (ES) is as an interface between a complex computer model and an inexperienced user or novice. The software is applied to the USEPA...
An Expert System for Snowmelt Runoff Modeling and Forecasting
An expert system has been designed and is being built for predicting snowmelt runoff. The expert system mimics an experienced hydrologist by assisting the user in preparing data input,...
Incorporating Judgment into an Optimization Model of a Wastewater Treatment System
The use of design variable constraints according to textbook and state design standards might cause potentially good designs to be missed and would not capture the fuzzy interaction of...
Expert Systems in Reservoir Management and Planning
Recent advances in artificial intelligence techniques have created a mechanism for incorporating empirical knowledge into algorithmic reservoir planning and management models. The authors'...
Expert Pattern Recognition for Pollution Source Identification
This paper presents an approach for developing an Expert System to aid the identification of locations and magnitudes of a finite number of groundwater pollution sources. A pattern recognition...
Debris Flows and Hyperconcentrated Streamflows
Examination of recent debris-flow and hyperconcentrated-streamflow events in the western United States reveals (1) the topographic, geologic, hydrologic, and vegetative conditions that...
Recovery of Freshwater Stored in Saline Aquifers in Peninsular Florida
Subsurface freshwater storage has been operationally tested at seven sites in central and south Florida. Injection was into a high chloride water aquifer at six sites, and into a high...
Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Lands
In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive...
America's National Forests: Our Ultimate Water Source
National Forest System lands in the western United States make up 21 percent of the total land area but yield over 55 percent of the region's streamflow and provide more than...
Water Management of the Snowy Mountains Scheme Australia
The Snowy Mountains Scheme in south-eastern Australia provides a classic example of Water Resources Planning and Management on a National scale. The Scheme provides mainly peak electricity...
River Basin Network Model for Conjunctive Use of Surface and Groundwater
A generalized river basin computer model called CONSIM is presented for management of the conjunctive use of surface and subsurface storage in an interconnected stream-aquifer system....
Optimizing Drain Spacing and Depth Using Steady State Equations
A method is developed for minimizing the total cost of establishing relief drains by choosing appropriate depth and spacing of the drains. Solution graphs are presented for a wide range...
A GIS to Predict Non-Point Source Pollution Potential
The non-point pollution potential of agricultural lands was analyzed using a geographic, computer based system. Bacterial pollution received special emphasis. The system accepts digitally...
A Customized Database Management System for Watershed Modeling
When large watershed areas are being studied and continuously monitored, it is desirable to create a database management system (DBMS) that provides the necessary capability to build and...
Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...
Water Infrastructure Maintenance Needs?A Case Study
Adoption of measures to prevent loss of water in many cases is cost-effective. In order to illustrate the magnitude of infrastructure problems of large cities, a test case infrastructure...
Modernizing the Maintenance Function
The Los Angeles County Department of Public Works maintains one of the largest and most complex flood control and water conservation systems in the world. A system study of the maintenance...
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Port Infrastructure Program in Mexico
In Mexico the policies, guidelines, goals and methodologies refering to transport, are the responsibility of the 'Secretaria de Comunicaciones y Transportes'...
